php - angular-laravel create users gives a query exception -

i'm trying create new users in basic laravel-angularjs app. i'm getting 500 server error , upon looking further there's query exception. i'm passing text value password hashed. error because of this?

angular controller:

user.saveusers({           "first_name":um.firstname,           "last_name":um.lastname,           "admin":um.admin,           "email":um.email,           "password":um.password         }).then(function(success) {            console.log(success);         }, function(error) {           console.log(error);         });  

the laravel controller:

public function store(request $request)     {         //         $data = request::all();          $users = new user();          $users->fill($data);          $users->save();     } 

users.php:

 protected $fillable = ['first_name','last_name','admin', 'email', 'password'];  protected $hidden = ['password', 'remember_token', 'created_at', 'updated_at']; 

table structure:

create table "users" ("id" integer not null primary key autoincrement, "first_name" varchar not null, "last_name" varchar not null, "admin" tinyint not null, "email" varchar not null, "password" varchar not null, "remember_token" varchar null, "created_at" datetime not null, "updated_at" datetime not null)
